Composition of Baldwinsville gas 



Acetylene .00 



Hydrogen (by the palladium method) trace 



Marsh gas 98 . 40 



Carbon monoxid .95 



Carbon dioxid .00 



Illuminants, diffused .25 



Oxygen trace 



Nitrogen, by difference .40 



100.00 



Specific gravity, by calculation, .558 



Heat units a cubic foot, 1013.5 



Odor faint, resembling crude Pennsylvania petroleum. 



These figures may be taken with all confidence as representing 

 the composition and specific gravity of the Trenton limestone 

 gas of New York. 



In 1886-87 Prof. C. C. Howard of Columbus, O., made a num- 

 ber of analyses of the gas from the new fields of Ohio and Indiana 

 and reported 92f to 94^ of marsh gas, but also reported about 

 Zf of nitrogen, 2 c / of hydrogen, together with a small amount 

 of carbon dioxid. Prof. Howard afterward found reason to sus- 

 pect that these latter figures were the result of erroneous meth- 

 ods of analysis, but did not have opportunity to repeat his work 

 and eliminate the doubtful points, tie also calculated on the 

 same basis the specific gravity of Findlay gas and made it .566. 

 If the corrections suggested should be found necessary, they 

 would, when made, bring the composition and gravity of the 

 Ohio gas to agree closely with Dr Woodman's figures for the 

 gas of New York from the same stratum. 



The only important difference between the production of the 

 two fields would be found in the sulfur contents of the Findlay 

 gas. This element does not occur in the gas of New York from 

 the Trenton horizon. In Ohio and Indiana the sulfureted 

 hydrogen of the gas is very noticeable and offensive. According 

 to Prof. Howard the sulfur of this compound amounts to 1.25 

 grains to the cubic foot of Findlay gas.
